A birthday cake topper is a decorative item placed on the top of a birthday cake. It can be made from various materials, such as plastic, paper, or fondant, and often features themes or designs that reflect the birthday person's interests or age. Common examples include balloons, candles, or characters from popular culture. These toppers serve both aesthetic and celebratory purposes, enhancing the cake's appearance and making it more festive. They can be customized to match the party's theme or the individual's personality, adding a personal touch to the celebration.
